Abstract (en)
[origin: US2022153933A1] A polyorganosiloxane with an epoxy group, a curable resin composition, and a cured product having high compatibility with an initiator and another resin is described. The polyorganosiloxane has a low viscosity, a high curing rate, and high adhesiveness and impact resistance. The polyorganosiloxane has an M unit (R1R2R3SiO1/2), a D unit (R4R5SiO2/2), and a Q unit (SiO4/2). A T unit (R6SiO3/2) content of the polyorganosiloxane is 80% or less by mole of total silicon. The epoxy group has a group of formula (2) and a group of formula (3). Here, R8 is an optionally substituted divalent organic group having 1 to 20 carbon atoms, g is 0 or 1, R9 is an optionally substituted divalent organic group having 1 to 20 carbon atoms, h is 0 or 1, 0≤i≤8, and 0≤j≤8.
